sporadic app crashes when picking a custom emoji during post creation

[Stefan240]

First some words on my setup. My instance runs akkoma on the stable branch and moshidons seems to do really great normally.

Describe the bug

The app tends to sporadically crash when I type in a shortcode for a custom-emoji. Normally I don't type out the whole name of the emoji but for a blobcat I would use something like :blob and then pick the correct emote I want. Sometimes but not reliably the app would crash for me. Funnily enough the app now that I am writing this report refuses to crash because of course lol.

To reproduce

Steps to reproduce the behavior:

1. start writing a reply or post
2. start searching for a custom-emoji you want to add to the post by typing :someemojiname
3. Pick emoji from given list.
4. App crashes sometimes.

Does this happen in the official app?

There is not really an official app for akkoma and mastodons app is not really usuable for this. I did not try megalodon though. The function does work as expected on the web-frontend akkoma-fe though.

Version

Moshidon version: [e.g. v2.1.4+fork.103.moshinda]

Crash log

btw thank your for adding the ability to collect crash logs so easily ❤️ This one is the most recent I got. i wanted it to crash again before posting just to be safe but it kinda is behaving atm.

This is seems also to be an issue with megalodon. See here: sk22#920

[nodeunit]

I can confirm similar behavior when using the emoji picker or @ mention search. Usually it is triggered if I invoke the emoji picker with :, start writing the name of an emoji, and then start deleting text. It is guaranteed to crash if I fully dismiss the picker bar by deleting all text, and then shortly after invoke emoji search again.

Here's my logs:
